Abstract: The miscibility of polyacrylonitrile (PAN) with four tertiary amide polymers was studied. Each of the binary blends of PAN with poly(N-vinyl-2-pyrrolidone) (PVP), poly(N-methyl-N-vinylacetamide) (PMVAc), or poly(N,N-dimethylacrylamide) (PDMA) showed a single glass transition temperature (Tg), indicating miscibility. However, PAN is immiscible with poly(2-ethyl-2-oxazoline) (PEOx) as shown by the appearance of two Tgs in each of the blends. Based on the frequency shifts of the carbonyl band of the tertiary amide polymer and the cyano band of PAN the intensity of intermolecular interaction between PAN and tertiary amide polymer is in the order PVP > PMVAc > PDMA > PEOx.
